TRANSCRIPT
Slide 1SBU-T
Para 5.3.5 of the National Electricity Policy notified by the Ministry of Power, Government of India,
under Section 3 of the Act vide Resolution No.23/40/2004-R&R (Vol.II) dated 12.2.2005 provides as
under:
“5.3.5 To facilitate orderly growth and development of the power sector and
also for secure and reliable operation of the grid, adequate margins in
transmission system should be created. The transmission capacity would be
planned and built to cater to both the redundancy levels and margins keeping in
view international standards and practices. A well planned and strong
transmission system will ensure not only optimal utilization of transmission
capacities but also of generation facilities and would facilitate achieving
ultimate objective of cost effective delivery of power”.
• The growth of transmission system must be ahead of generation both
in time and capacity to avoid congestion or bottling up of power.
• Efficient operation of transmission system in terms of providing
reliability, avoidance of disturbance, maintaining voltage level and
reducing transmission losses requires continuous strengthening of
transmission system.
Transmission Planning
• Provide 24 x 7 power supply to all consumers with n-1 and n-1-1 and
n-2 reliability.
• With Open Access in transmission, the role of transmission has
changed from a mere infrastructure to an enabler in operation of a
competitive power market.
Transmission Planning Objectives
The power requirement of the state has been increasing rapidly in the
past decades.
The maximum demand has crossed 4000 MW in 2016 (27-April-
2016).
The demand is expected to rise to 4,900MW within the next five
years

comprehensive transmission development scheme named TRANSGRID 2.0has been developed
to relieve the system of its present constraints, building sufficient import capability for the
future, facilitate complete power evacuation from generating stations within the state, to
reduce transmission losses to the possible maximum while fully meeting power demand of the
state. The project requires a total investment plan of about Rs. 6,375Cr within 5 years

The loading pattern in the existing 110/11kV AIS Tirur, having
capacity of 52.5MVA {2x20MVA + 1x12.5MVA} has reached its
safe loading limits and hence either the station capacity need to be
enhanced nor new substation has to be built in to cover up the future
power demand.
existing transformers at Tirur 110kV AIS were 70% and 53%
respectively in the year 2015, which has now increased to 85% and
75% respectively.
The proposed scheme will also mitigate the high loading of the
110kV DC feeder from 220kV Substation Areekode to Keezhissery.
Under the non-availability of this scheme any failure / fault in the
above 110kV corridor or at 220kV Substation Areekode can plunge
Malappuram and adjoining areas into black out state.

Remarks
Para 5.3.5 of the National Electricity Policy notified by the Ministry of Power, Government of India,
under Section 3 of the Act vide Resolution No.23/40/2004-R&R (Vol.II) dated 12.2.2005 provides as
under:
“5.3.5 To facilitate orderly growth and development of the power sector and
also for secure and reliable operation of the grid, adequate margins in
transmission system should be created. The transmission capacity would be
planned and built to cater to both the redundancy levels and margins keeping in
view international standards and practices. A well planned and strong
transmission system will ensure not only optimal utilization of transmission
capacities but also of generation facilities and would facilitate achieving
ultimate objective of cost effective delivery of power”.
• The growth of transmission system must be ahead of generation both
in time and capacity to avoid congestion or bottling up of power.
• Efficient operation of transmission system in terms of providing
reliability, avoidance of disturbance, maintaining voltage level and
reducing transmission losses requires continuous strengthening of
transmission system.
Transmission Planning
• Provide 24 x 7 power supply to all consumers with n-1 and n-1-1 and
n-2 reliability.
• With Open Access in transmission, the role of transmission has
changed from a mere infrastructure to an enabler in operation of a
competitive power market.
Transmission Planning Objectives
The power requirement of the state has been increasing rapidly in the
past decades.
The maximum demand has crossed 4000 MW in 2016 (27-April-
2016).
The demand is expected to rise to 4,900MW within the next five
years

comprehensive transmission development scheme named TRANSGRID 2.0has been developed
to relieve the system of its present constraints, building sufficient import capability for the
future, facilitate complete power evacuation from generating stations within the state, to
reduce transmission losses to the possible maximum while fully meeting power demand of the
state. The project requires a total investment plan of about Rs. 6,375Cr within 5 years

The loading pattern in the existing 110/11kV AIS Tirur, having
capacity of 52.5MVA {2x20MVA + 1x12.5MVA} has reached its
safe loading limits and hence either the station capacity need to be
enhanced nor new substation has to be built in to cover up the future
power demand.
existing transformers at Tirur 110kV AIS were 70% and 53%
respectively in the year 2015, which has now increased to 85% and

Malappuram and adjoining areas into black out state.
This project is proposed to build necessary
downstream side infrastructure to evacuate power
from PGCIL HVDC station at Mannuthy
offering a stable, reliable and alternate power
transmission and distribution network in the
Malappuram District
central and southern regions {Aluva-North Paravur-
Kodungallur-Irinjalakuda-Kunnamkulam-Vengallur}
Project cost is Rs. 204.18 Cr Date of COD: 2021-22
